Document Content and Description Below
2. Explain how the wavelengths absorbed and reflected determine the color of a pigment. Pigment is responsible for absorbing light. Color of pigment comes from the light is not absorbed. Chlorophyll... is green in color because it absorbs all wavelengths of light except green. 3. Take a look at the overall reaction for photosynthesis and suggest two ways that the rate of photosynthesis could be measured (Hint: Consider how the substrates and products will change throughout the course of the reaction.) 6 CO2 + 6 H2O + Light Energy → C6H12O6 + 6O2 You could meause by CO2 uptake or production of O2 4. Many deciduous trees have leaves that turn yellow in the fall. What is happening in the leaves at the cellular and molecular level that is responsible for this color change? Break down of chlorophyll is responsible for yellow color. Also, anthocyanin causes yellow color of the pigment. 5. Chloroplasts are the organelles in plant cells that convert solar energy to chemical energy (sugars) that can be used by the cell. Mitochondria are organelles in all eukaryotic cells that convert sugars to ATP Both organelles are have double membranes and contain their own set of DNA. What is the likely explanation for this?
